Co-ordinate Control for Fuel Cell And Photovoltaic Cell

Gurram Nookaraju, S. Gangadharan, B. Subbareddy


The usual natural fuel energy resources such as petroleum, natural gas, and coal are getting shortage rapidly by fulfilling the high demand of the energy sector in the world. Also, affect the environment and leads to the greenhouse effect and serious pollution problem. Therefore renewable energy sources like solar, wind, tidal etc. are gaining more attention as an alternative energy.

The hierarchical structure of the convention power system is experiencing a paradigm shift into a deregulated system. As a result many small generators are been connected to the system at the distribution level. In order to supply a reliable and sustainable power to select customers it becomes mandatory to connect renewable and dispatchable sources. This would result in a hybrid system which can operate in autonomous or non-autonomous mode. This project aims at analysing the performance of one such autonomous system for varying demand. PV and fuel cell sources are considered to form the hybrid system under concern.

An overall coordinated controller has been analysed to ensure power sharing among the different sources used in the hybrid system also incorporating variations in the solar irradiations. Also a simulation for generation of pulses for appropriate switching of control between the different sources through MATLAB has been attempted in this work.
